I had been taking hydrocodone7.5 for about a yr they got to where they didn't work as well as when i first started them so my Dr changed my medicines to the Butrans patch 10mg I have been on it for 22 days and I can't tell a difference at all I am taking 12 Advil and 9 Excedrin Migraine every day and still have some pain. What should I do? It isn't helping me at all
